The acting director of the Center for Disease Control and Prevention said on Monday that an employee who went missing over a month ago was not recently passed up for a promotion, as police had previously reported. Timothy Cunningham, a highly regarded epidemiologist at the CDC, disappeared without a trace after he left work mid-day on Feb. 12, complaining of feeling ill. Atlanta Police Department Major Michael O’Connor had initially said that on the morning of Cunningham’s disappearance, the 35-year-old doctor spoke with his supervisor about a promotion that he didn’t receive and expressed disappointment to several coworkers about being passed up for the position.
